Organotin formation

Organotin chemistry is the scientific study of the synthesis and properties of organotin compounds or stannanes, which are organometallic compounds containing tin carbon bonds. The first organotin compound was diethyltin diiodide ((CH3CH2)2SnI2), discovered by Edward Frankland in 1849. … Zobacz więcej Organotin compounds are generally classified according to their oxidation states. Tin(IV) compounds are much more common and more useful. Organic derivatives of tin(IV) The … Zobacz więcej Organotin compounds can be synthesised by numerous methods. Classic is the reaction of a Grignard reagent with tin halides for … Zobacz więcej An organotin compound is commercially applied as stabilizers in polyvinyl chloride. In this capacity, they suppress degradation by removing allylic chloride groups and by absorbing hydrogen chloride. This application consumes about 20,000 tons of tin each … Zobacz więcej • Organostannane addition • Tributyltin azide • Carbastannatranes Zobacz więcej Important reactions, discussed above, usually focus on organotin halides and pseudohalides with nucleophiles. In the area of organic synthesis, the Stille reaction is considered important. It entails coupling reaction with sp -hybridized organic halides (e.g. Zobacz więcej The toxicities of tributyltin and triphenyltin derivatives compounds are comparable to that of hydrogen cyanide. Furthermore, tri-n-alkyltins are phytotoxic and therefore cannot be used in agriculture.
